For edge repair on the go the Toko Express Tuner Kit is the tool you need. You can easily resharpen your edge and create 87° or 88° angles.
Includes a 40mm tuning file and a spare coarse diamond file that can be stowed away in the tool.
When repairing an edge , the diamond stone is used first to remove any burring of the edge, this prevents blunting the file.
